FIELD: electricity.
SUBSTANCE: invention relates to automation of electrical networks. Result is achieved by providing the possibility of seasonal backup of consumers connected to the same network, based on the need for backup, taking into account the calendar date and time of day. In addition, when the main source of power supply is disconnected, consumers whose power supply does not need to be backed up are disconnected from the network, and their connection to the network is blocked, consumers are connected to the network, the power supply of which is to be backed up, and when the main power supply source is switched on again, the blocking of connection of consumers to the network is removed and all consumers are connected to the network.
EFFECT: improving reliability of power supply to consumers and functionality of seasonal backup methods.
